6 NJ44 *Input Capacitor C IN The input capacitor C IN is required in order to prevent oscillation and reduce power supply ripple of applications when high power supply impedance or a long power supply line. Therefore, the recommended capacitance (refer to conditions of ELECTRIC CHRCTERISTIC) or larger input capacitor, connected between and GND as short path as possible, is recommended in order to avoid the problem. *Output Capacitor C O The output capacitor C O is required for a phase compensation of the internal error amplifier, and the capacitance and the equivalent series resistance (ESR) influence stable operation of the regulator. If use a smaller output capacitor than the recommended capacitance (refer to conditions of ELECTRIC CHRCTERISTIC), it may cause excess output noise or oscillation of the regulator due to lack of the phase compensation. Therefore, the recommended capacitance or larger output capacitor, connected between and GND as short path as possible, is recommended for stable operation. The recommended capacitance may be different by output voltage, therefore confirm the recommended capacitance of the required output voltage. Furthermore, a larger output capacitor reduces output noise and ripple output, and also improves Output Transient Response when a load changes rapidly. Selecting the output capacitor, should consider varied characteristics of a capacitor: frequency characteristics, temperature characteristics, DC bias characteristics and so on. Therefore, the capacitor that has a sufficient margin of the rated voltage against the output voltage and superior temperature characteristics, is recommended for C O. *Transient Response of Output Voltage In general, the regulator tends to cause overshoot or undershoot of output voltage at the following conditions. Particularly in products featuring low current consumption, the output voltage fluctuation may become large due to product characteristics. hen input voltage or output current fluctuate sharply hen output capacitance is small hen output load is light hen start up from the condition of narrow voltage difference between an Input and an output. One way to improve transient response is to use a large capacity input and output capacitors to suppress to the fluctuation. mount of transient fluctuation will change according to multiple conditions, so please refer to the above to confirm with actual equipment.
